patience.... no need to bump the thread after 1h

Take a look at the QtHelp module for example.

Save the pdf file inside your resources (.qrc files) then you can open them via:

QString destinationTemp = QDir::fromNativeSeparators(QDir::tempPath());
if(!destinationTemp.endsWith('/'))
destinationTemp.append('/');
QString fileName = "manual";
if(QFile::exists(destinationTemp + fileName + ".pdf"){
fileName  = "manual %1";
unsigned int i=0
for(;QFile::exists(destinationTemp + fileName.arg(i) + ".pdf");++i){}
fileName  = fileName.arg(i);
}
QFile::copy(":/docs/manual.pdf",destinationTemp + fileName   + ".pdf");
QDesktopServices::openUrl(QUrl::fromLocalFile(destinationTemp + fileName   + ".pdf"));

P.S.
this is not the first time you are warned not to bump the topic too fast, let's make it the last, shall we?!

Thanks to all.
I got simple solution to open PDF file on Windows System through QT.
Save your pdf file in Build directory then you can open them via:

QDir dir;
QString path = dir.absolutePath();
path.append("/Manual.pdf");
QDesktopServices::openUrl(QUrl::fromLocalFile(path));

its work fine for me.

@Pranit-Patil You don't specify explicitly where to store the file. I guess it will be current working directory. If this directory is not writeable by the user it will not work. You should use http://doc.qt.io/qt-5/qtemporaryfile.html

@jsulm i mention Save pdf file in Build Directory.

@Pranit-Patil Sure, but what will happen when you deploy/install your app?
